People need to stop thinking this is all about Xbox trying to outsell PS. Its about Xbox trying to sell more consoles and games. PS4 doesnt need marketing to outsell the X1, the generation has already spoken. PS4 will outsell the X1 even with anti consumer practises and censorship etc. They could release mediocre games and still outsell the X1. Its a sad reality.
Xbox need E3 to recreate there brand where as PS doesnt. Having marketing rights wont affect Sony but it will help Xbox.
I guess it's good that Sony feels the need to release quality titles. Something Xbox should definitely try to do more of if they wish to improve their situation next gen.
Not sure what anti-consumer practises you speak of. I'm guessing it's something subjective that not all obviously agree with you on.
